Including a high-pressure pump (16) associated with a quantity controlling valve (15) having a solenoid valve (22) electromagnetically actuatable by a coil (21) for supplying fuel, the quantity control valve (15) controlling the quantity of fuel supplied by the high-pressure pump (16) and the coil (21) of the solenoid valve (22) having a first current value applied thereto, in order to close the same for supplying fuel to the high-pressure pump (16), the first current value being reduced to a second current value when the solenoid valve is closing (22), such that the radiation of audible sound arising from the closing of the solenoid valve (22) is at least partially reduced.

Abstract: In a fuel injection system of an internal combustion engine, fuel is delivered from a high-pressure pump into a fuel rail. The quantity of the delivered fuel is influenced by a quantity control valve which is activated by an electromagnetic actuating device. The level of control of the quantity control valve during the transition from the closed state to the open state of the quantity control valve is provided in the form of a sufficiently flat, descending progression which allows a robust control of the opening motion with regard to the varying specimen properties.

Abstract: In a method for controlling a quantity control valve, at least two parameters characterizing the quantity control valve are utilized. A control signal supplied to the quantity control valve is defined by the at least two parameters. At least one parameter is ascertained based on the result of a first adaptation and a second adaptation, or based on the result of a first adaptation and the other parameter.

Abstract: A method for regulating a fuel injection system of an internal combustion engine, wherein the fuel injection system includes a high-pressure pump which is associated with a quantity control valve having a solenoid valve electromagnetically operable by a coil for supplying fuel, the quantity control valve regulating the fuel quantity pumped by the high pressure pump and the coil of the solenoid valve being energized according to a setpoint current value in order to close the valve for supplying fuel to the high-pressure pump; when the solenoid valve closes, the setpoint current value is reduced from a first current setpoint value to a second current setpoint value so that an emission of audible noise generated when the solenoid valve closes during operation of the internal combustion engine is at least partially reduced.
